Day 4: Ocean Beach / Fort Funston

Dollar Tree: I never realized that this branching tree pattern was on the bottom of sand dollars. As you can see in the next few photos, this pattern is repeated a lot in nature!

Sea Tree: This seaweed has the same branching pattern as the sand dollar. Besides the pattern, I also like how I framed this shot.

Sand Tree: The erosion pattern in the sand also branches like a tree. What’s interesting is that this pattern grows in reverse from a tree–starting with the branches and combining to create the trunk.

Foam Tree: The breaks in the sea foam also branches! You can see a lot of similarity in the polygons created by the breaks as well.

Rock Tree: Okay, so there aren’t really any tree patterns here, but there always has to be an oddball. I really like how the tides have shaped these rocks into such an interesting way and created this very neat arch. Is the arch 1 foot tall or 10? Also, notice the spiral swirls in the foam.
